How can I treat my water to remove radon?
The most effective treatment device to remove radon from drinking water is a point-of-entry (POE) device. A POE device removes contaminants immediately before they enter your home (Radon in Drinking Water: Questions and Answers, EPA815-F-99-007, October 1999). There are two types of point-of-entry devices that remove radon from water: - Granular activated carbon (GAC) filters which use activated carbon to remove the radon - Aeration devices which bubble air through the water and carry radon gas out into the atmosphere through an exhaust fan GAC filters tend to cost less than aeration devices; however, radioactivity collects on the filter, which may cause a handling hazard and require special disposal methods for the filter. For more information on aerators and GAC filters, you should contact two independent, non-profit organizations: NSF International at (800) 673-8010 and the Water Quality Association at (630) 505-0160.
